Ions with a single electron such as He+, Li2+, and Be3+, are explain by the H atom wave functions with Z/a0 substituted for 1/a0, where Z is a nuclear charge. The 1s wave function becomes? (r) = 1/vp (Z/a0)3/2e-Zr/a0. Using this result, compute the total energy for the first state in H, He+, Li2+, Be3+ by substitution in the schrodinger equation.
